Post-market Observational Clinical Study With the CE-marked Implantable Class IIb Medical Device "ITC CERVICAL"

The goal of this observational post-market study is to evaluate the clinical performance and safety of the ITC CERVICAL device, a CE-marked implantable cervical interbody fusion cage, in adult patients undergoing anterior cervical discectomy and fusion (ACDF) for symptomatic cervical degenerative disc disease.

The main questions it aims to answer are:

1. Does the ITC CERVICAL device improve neck disability and pain after surgery? 2. Does the device demonstrate adequate radiological performance in terms of cervical alignment, implant stability, and fusion-related outcomes? 3. Is the device safe when used according to its intended purpose? Researchers will review retrospective clinical and radiological data from patients previously treated with the ITC CERVICAL device between 2020 and 2024. The outcomes assessed will include neck disability, pain intensity, neurological function, general health status, cervical lordosis, implant subsidence or migration, need for revision surgery, and the occurrence of adverse events.

Participants included in the study are adult patients who previously underwent two- or three-level ACDF surgery with implantation of the ITC CERVICAL device as part of routine clinical care. Clinical data collected before surgery, within 5 days after surgery, and at 3 months follow-up will be analyzed to assess the device's clinical benefits and safety profile.
